I field tested their initial design which was a 240 gr pistol bullet in their Raptor design. Devastating would be an under statement. Shown are two pics of a buck I took at 120 yards with 100 grains of loose 777 powder. Three petals exited the far side, while the 4th petal struck the edge of the off side shoulder blade cracking it inwards two inches and upwards 7 inches. The main body exited the buck but was snapped back into the wound channel by connective tissue. Once the petals snap off, it leaves a jagged "cutting edge" that continues to cause damage. Currently they produce several choices designed for M/L's and as usual, if your rifle likes them, they will kill with extreme prejudice. Try them, they are custom made projectiles that will take any animal in North America and *Africa.
* Use extreme caution when hunting dangerous game. I recommend only the most experience muzzle loader hunter and guide take those hunts.
